How to wake Ubuntu 20.04 running on external SSD after suspension?

ar flag

I'm running Ubuntu on a SanDisk Extreme Portable SSD. When I suspend it and want to wake it up, it shows a black screen with a cursor looks like this _ blinking on the top left. I suspect that when Ubuntu goes into suspend mode, there isn't power supply to the external SSD, is there a fix?

  • Acer Aspire 7
  • I7-8750h
  • Nvidia 1050
  • Dual boot Win 10 and Ubuntu

Your suspicion is correct and no, there's no "fix". Linux running from external drives is doable but has its limitations.

What happens if you type at that blinking cursor? Have you tried typing `reboot` and then enter?

Just tried, I wasn't able to type anything.

OK so your only option is to stop it going to sleep. And that does not seem like a normal feature SO you can investigate two Linux packages that I have used in the past to controll HDD so good luck. The packages are hdparm and/or tlp. You can guggle them or search here or even on https://wiki.archlinux.org

Go into your BIOS setting, under Power setting and change the sleep mode from "Windows"(if Windows was your previous OS)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
